PORTABLE GAS-HEATER.

Specification of Letters Patent.

Patented July 13,1920.

Application filed June 5, 1918. Serial No. 238,270.

To all whom it may concern:

Be it known that I, PETER BnRNsrnIN, a citizen of the United States, residing at Boston, in the county of Suifolk and State of Massachusetts, have invented new and useful Improvements in Portable Gas-Heaters, of which the following is a specification.

This invention relates to improvements in portable gas heaters and has for its object to provide an inexpensive efficient heater adapted to be placed Within one of the rooms of an apartment or house andsupply heat to the rooms of said apartment.

Still another object of the invention is to provide air tubes which are made readily and easily detachable to facilitate the movements of the heater from the room when desired.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claim.

Referring to the drawings:

Figure 1 is a vertical section of a gas heater embodying my invention.

Fig.2 is a section taken on the line 2-2 of Fi l.

l ig. 8 is a detail perspective view illustrating the means for detachably connecting the air tube with the heater.

Like numerals refer to like parts in all views of the drawings.

In the drawings,'l is the inner casing of a heater which forms a compartment 2 containing the burner 8, said casing being closed at the lower end, as at l, and at the upper end by a cover 5, provided with a discharge opening 6 through which the products of combustion from within the chamber 2 may be conveyed through a suit able pipe 7 preferably to a chimney or, if desired, may be discharged through an opening in the outer wall of the house or one of the windows of said house.

The burner 3 is preferably arranged in the bottom of the compartment 2 and may be constructed in accordance with any of the burners at present used in connection with gas ranges or the like. The flames from the burner 3 are preferably deflected outwardly against the side walls of the easing 1 by means of a suitable plate 8 mounted above said burner and supported by brackets 9 secured to the casing 1 in such a way as to provide an opening 10 entirely surrounding said plate 8 through which the heat from the burner may pass upwardly.

Surrounding the casing 1 and at a substantial distance therefrom is an outer casing 11 which provides a second compartment 12 extending entirely around said inner casing and closed at the bottom by means of the wall i and at the top by means of a plate 13. The compartment 12 may be subdivided into a number of heating chambers 34 corre spending with the number of rooms to be heated by the device. In the present in stance said compartment is divided into SIX chambers by substantially radially disposed partitions 14. Each of these smaller chambers is provided with an air inlet opening 15 arranged near the bottom thereof, and an air outlet opening 16 disposed near the upper portion of said chamber.

Over each of these openings are detachably secured air conducting tubes 17 and 18 respectively, each of which tubes is preferably fiexible and attached to a plate 19 adapted to be inserted between guides 20, 20 formed upon opposite sides of the openings 15 and 16.

W hen any of the smaller chambers 34 are not required for heating purposes, the plates 19 may be removed and plates without holes inserted in place thereof to entirely close said openings, and by so doing more heat will be available for the other heating chambers, or when the heater is to be employed to heat only one room, the plates and the tubes connected therewith may be removed and the air will then be drawn from the room through the opening 15 and discharged from the top of the casing through the opening 16 directly into the same room.

When the heater is to be used in heating a number of rooms, the tubes 17 and 18, being small and flexible, may be extended from the heater in practically any direction and suspended, by means such as hooks 35, from the walls or ceilings of the rooms and passed through small openings made in said walls or ceilings to the adjoining rooms, so that air may be drawn from the adjoining rooms into the heating compartments through the lower opening 15 and discharged or conveyed from said heating chamber through the tube connected with the upper opening 16 back into the room from which said air was taken.

To facilitate the heating of the air as it passes through the several subdivisions of alternate so that the air passing'upwardly n will be deflected from side to side and thereby greatly retard theprogress of said air so that it will have a better chance to be heated during its passage through said heatving chambers.

The mixing chamber of the burner 3, as shown at 23, is constructed in the usual well known manner and consists of a gas supply tube 24 provided withashut off valve 25 which is arranged toextend into the mouth of an air'pipe 26. to which air is supplied through a flexible tube 27 constructed of rubber or other suitable material and adapted to supply air from a point outside of the room within which the heater is arranged. A valve 32 is arranged in said tube 27 for regulating the supply of air to the burner.

A convenient method of supplying fresh air to said burner is shown in Fig. l of the drawings and consists in providing a cou-- pling 28 at the outer end of the tube 27 and this is adapted to fit into a hole 29 formed in the lower portion of an outer window sash 80 so that the air may be drawnthrough the opening 29 from outside of the room, or house, but when the device is not in use, the coupling 28' may be Withdrawn from the opening 29 and said opening closed by any suitable means, such as by a plate 33 pivotally mounted on said sash.

The heater is provided with suitable casters or trucks 31 so that the same may be 7 more easily moved from place to place. There are many advantages connected with the use of a heater of the nature hereine before specifically described over the well known steam and hot water heaters for fur:

be dispensed with, the heater may be set up in one of the rooms to be heated, and the flexible tubes extended to the variouspoints of distribution, thus saving a large amount of heat, and furthermore, the device may be moved to some remote or unused portion of the apartment or house when not required. v

Furthermore, by reason of the method of supplying air forcombustion, the oxygen of the room within which the heater is arranged will not be exhausted'or rendered impure and all odors from the burning gas will be carried off through the discharge pipe 7 so that no inconvenience will result from the fact that the heater is operated in one of theliving, or sleeping rooms of the house. V c

Having thus specifically described my invention, what I claim and desire by Letters Patent to secure is: a

A portable gas heater having, in combination,.a combustion chamber provided with a closed outer wall, a plurality of independent fheating chambers surrounding said combustion chamber, a gas burner located within said combustion chamber, a plate located above said gas burner and adapted to deflect the heat therefrom against the closed wall of said combustion chamber, a plurality of horizontally disposed baffle plates located within each of said heating chambers, inlet and discharge openings for each of said heating chambers, and flexible air tubes connected respectively with said inlet and discharge openings and adapted to convey heated air from each of the heating chambers to a room to be heated andto carry air from said "room back to the heating chamber.

In testimony whereof Ihave hereunto set my hand in presence of two subscribing witnesses.
